Application filed AAugust 24, 1916. Serial No. 116,646.

with regard 'o other parts of the machine as well as to the pattern on the paper or other web already printed, and in accomplishing this result, much time and labor have hitherto been necessary.

One object of my invention therefore is to provide a relatively simple, substantial andl conveniently operative device whereby each of a succession of print rollers may be quickly and conveniently adjusted in the machine to bring its design into precisely/the position desired. J

Another object of the invention is to pro vide a device which may be inexpensively applied to roll printing machines for the purpose of quickly and conveniently positioning print rolls both longitudinally and cireumferentially in order to bring their patternsinto a predetermined relation with regard to another part of the machine and hence to a previously printed pattern.

These objects and other advantageous ends l secure as lhereinafter set forth, reference being had to the accompanying drawings, in which,

Figure 1 is a side elevation, partly in vertical section. illustrating the preferred forln ol'v my invention; and

Fig'. 2 is an end elevation of the apparatus shown in `Eng. 1.

In the above drawings 1 represents a portion of one of the side frames of ,a r'ollv printing machine having-a bearing' portion 2 in which is journaled one end of the shaft 3 designed to support and rotate the successive print rollers. On this shaft is fixed a gear wheel i which is driven at a suitable speed by means forming no part of this invention but including a toothed member meshing with it. l

Threaded on the shaft y3 is an adjusting nut or collar 5 having a tapering or conical extension A(3 designed to fit into the opening of the shaft in either direction and clamped in any given position.

For predetermining the position in whichy each roll is to be set or clamped, l mount on the frame l a pair of parallel bars S) and 10 on which are mounted three slides 11, 12 and 13. The first of these is provided with a thumb screw 14 whereby it may be rigidly clamped to the bar 10 in any given position and in addition it is provided with a guideway for the reception of a rod 15 which is slidable thereon in a line at right angles to the bars 9 and 10. This rod has a stud or screw 16 projecting from it through a'slot 17 in the guideway and on said stud is a thumb nut 18 whereby said rod may be clamped in any adjusted position. The rod at its lower or inner end carries a head 19 which slidably guides a pointed pin or rod 20 movable in a line at right angles to said first rod and capable of being retained in position by a screw 21 passing through a slot 22 in said head and held in place by a thumb nut 23.

The gear l on the shaft 3 has set in its side or web portion, adjacentv the print roll, a small plug or block 24 having' a conical recess designed to 'receive the similarly shaped end of the pin or rod 20.

The slide 13 has a set screw 25 whereby it may be rigidly' clamped to the bar 10 and has rotatably mounted in it a threaded stud 26 which enters the slide 12, the arrangement being such that rotation of the stud moves the slide 12 upon the bars 9 and l0. Said slide is provided with a guideway for the reception of a pointed bar 27 and each of theprint rolls 8 has set in its cylindrical surface a metal plug or block 2S whose outer face lies flush with said roll. Tn said face is a conical recess designed to receive the .pointed end of the rod 27 which has set in it a stud 29 extending through a slot 3() in the slide 12. This has a thumb nut 3l whereby said rod 27 may be clamped in any given position.

ln using my invention, the shaft 3 with the gear wheel 4 is mounted in place, with the block 24: of said gear in that particular definite position relatively to the frame 1 which it is desired that said shaft as well as any other shaft having a similar gear wheel; shall thereafter occupy. The slide 11 with the rod 15 and pointer 2D are then so adj usted that the end of said pointer enters and fits the recess in the plug 24 of said gear Wheel, after which the nut 23 on the screw 2l as Well as the nut 18 on the screw 16 are tightly set up so as to hold these parts in their adjusted positions.

The slides 13 and 12 are Inovv moved upon 4 the guide rods 10 and 9 until the latter slide occupies a position with its rod 27 'approximately in the radial line through the plug 28 of the print roll, which by adjustinp;LV the nuts 5 on the shaft 3 has been previously moved until the pattern upon its surfaceoccupied the relative position which it is desired the patterns on subsequent rolls shall occupy. The screw 25 is then set up', thus clamping said slide 13 rigidly in place, and with the thumb nut 31 loosened, the screw 26 is so manipulated as to shift the slide 12 until the point of the rod 27 fits into the recess of the plug 28.

After the shaft 3 with the roll 8 has been removed and replaced by a second print roll and its associated parts, the latter is `first turned on its longitudinal axis until the pointer 20 may enter the recess of the plug j 241e` of the gear Wheel 4 on said sha-ft. The

roll 8 is then so adjusted by means of its nuts 5 and is also so turned upon the shaft, that the pointer 27 may bepcaused to fit into the recess of the plug 28; which as Well as the plug 24 of the gear Wheels, occupies denite positions relatively to the pattern on said rolls. As a result of thissetting, when any gear wheel and roll have been brought to the positions relative to the pointers 20 and 27 shown in F ig. l, the pattern of said roll occupies a predetermined position relatively to the other parts of the machine and to the pattern to be printed.

Obviously the adjustments of any roll in order to obtain the above desired results may be quickly made with the utmost ease, Where hitherto it has been necessary to adjust such rolls merely by an experimental' method Which required considerable time and hard labor. l

l/Vhen it is desired to operate the machine, the pointers-2O and 27 are Withdrawn from the recesses in the blocks or plugs 2e and 28 by loosening their clamping; screws 23 and 31 and withdrawing them to retracted positions in which they are clamped until required in positioning another roll. Withvided with holes 'or recesses designed to cogear and roll be pro- 4 operate with the lpointers as lpreviously dei scribed. Moreover While I preferably use holes or recesses to coperate with the 'pointers in locating a roll, it is possible that in some cases marks such as'crosses or= circles may be substituted for such holes Withoutdeparting from my invention.

1. The combination of a pointers a print rollg'a recessed plug set in said roll in a detinite position With regard to the pattern on the roll; and means for adjusting the roll to bring the recess, of its plug into a predetermined position relatively tothe pointer.

2. The combination of a pointer; a print roll;a recessed plug' set substantially flush with the curved surface of said roll in aV definite position relatively to the pattern thereon; and means for adjusting the roll to bring the recess' of the plug into yline with the pointer.

8. The combination of a supporting frame; a shaft rotatably'mounted therein; a member mounted on the shaft and having a recess extendingI in a line parallel to the shaft; a slide adjustably mounted on the frame; vvith an independently adjustable pointer carried by the slide in position to enter the recess of the member When-the latter occupies a. predetermined position.

4. The combination of a frame; a shaft rotatably mounted therein.; a member mounted on the shaft having a definitely placed recess extending parallel with the shaft; a guide member also parallel to the sha-ft; a slide adjustable on said guide member; a bar adjustably held t0 said slide and movable toward and from the shaft; Wit-h a pointer carried by said bar in position to coperate with the recess of the shaft-carried member when the latter occupies a predetermined position.

5. The combination of a supportingV frame including a guide; tivo slidesmovable' on said guide; means for clamping one of the slides to the` guide; means for adjustably connecting the second slide to the first slide; a pointer carried by the second slide and movable in a line at `right angles to that of the guide; a shaft rotatably mounted'inY the frame; a print roll on the shaft having a recess definitely placed With'relation to its pattern; and means for adjusting the roll on the shaft to bring its recess into a position to be entered by the pointer.
